# References and further reading

These are genuine, standard sources. No page numbers, fabricated DOIs, or invented
quotations are included. Where a specific edition is not stated, treat the entry as
a pointer to the work rather than a precise citation.

## Higher-dimensional geometry

- **H. S. M. Coxeter, *Regular Polytopes*.** The classic reference on polytopes in
  arbitrary dimension, including the hypercube and its symmetry and face structure.
- **Wolfram MathWorld, Hypercube Graph.** A concise reference for n-cube graph
  notation and low-dimensional projections:
  `https://mathworld.wolfram.com/HypercubeGraph.html`.
- **Thomas F. Banchoff, *Beyond the Third Dimension*.** A strong entry point for
  projections, computer graphics, and four-dimensional visual intuition. Online
  index: `https://www.math.brown.edu/tbanchof/Beyond3d/index.html`.
- **Edwin A. Abbott, *Flatland: A Romance of Many Dimensions*.** A 19th-century work
  of fiction, included only as a historical analogy for reasoning about dimensions
  we cannot directly perceive. It is a story, not a scientific source.

## High-dimensional data visualisation

- **A. A. Goodman, "Principles of high-dimensional data visualization in astronomy"
  (2012).** Useful context for why projections, linked views, and reduced
  representations matter in real astronomical data analysis. arXiv:
  `https://arxiv.org/abs/1205.4747`; DOI: `10.1002/asna.201211705`.

## Physics

- **A reputable general relativity textbook** for curved four-dimensional spacetime,
  Lorentzian signature, and the distinction between time and ordinary spatial axes.
- **A reputable introductory string theory textbook** for extra dimensions and
  compactification as theoretical frameworks rather than confirmed observations.
- **Particle Data Group, Review of Particle Physics.** Use the current PDG portal for
  up-to-date summaries of particle physics searches and constraints, including
  speculative extensions beyond the Standard Model: `https://pdg.lbl.gov/`.

## Tools

- **Three.js documentation.** Official documentation for the WebGL library used to
  render the scene: `https://threejs.org/docs/`.

## A note on sourcing

The atlas separates what is mathematically certain from what is physically
speculative. Exact hypercube counts come from elementary combinatorics; claims about
physical extra dimensions belong in physics references and experimental reviews, not
in the visual appearance of a projection.
